Answer:
The fraction of students who likes soccer or basketball is 7/10.
Step-by-step explanation:
In this case we have two groups of students, the group a is the one that prefers soccer, while the second group is the one that prefers basketball. We then need to find the fraction that represents the students that are in either group, in these cases we need to take the fractions of each group and sum them. So we have:
soccer OR basketball = soccer + basketball
soccer OR basketball = 2/5 + 3/10
Through LMC we have:
soccer OR basketball = (2*2 + 3)/10 = (4 + 3)/10 = 7/10
The fraction of students who likes soccer or basketball is 7/10.
Answer: the answer is 6
Step-by-step explanation: because 6/4 = 1.5 and 1.5• 6 =9
Answer:
slope = -1/4
y-intercept = 8
Step-by-step explanation:
In the equation y = -1/4 x + 8
The slope is -1/4 and the y-intercept is 8.
Linear equations are written like "y=mx + b"
"m" stands for slope.
"b" stands for y-intercept.
Answer:
x-intercept is (2,0) [The x-intercept means that it takes 2 hours for the temperature to reach 0°C]
y-intercept is (0, -6) [The y-intercept represents the temperature at sunrise, -6°C]
Step-by-step explanation:
<u>Complete Question:</u>
<em>The air temperature is -6 degrees celcius at sunrise and rises 3 degree celcius every hour for several hours. The air temperature after x hours is represented by the function f(x) = 3x - 6. Find the x-intercept and y-intercept and interpret their meaning.</em>
<em />
- The x-intercept is the x-axis cutting point found by setting y = 0 [function = 0]
- The y-intercept is the y-axis cutting point found by setting x = 0
Lets find x-intercept first:
f(x) = 3x - 6
0 = 3x - 6
3x = 6
x = 6/3
x = 2
x-intercept is (2,0)
Now, lets find y-intercept:
f(x) = 3x - 6
f(x) = 3(0) - 6
f(x) = -6
y-intercept is (0, -6)
The x-intercept means that it takes 2 hours for the temperature to reach 0°C
The y-intercept represents the temperature at sunrise, -6°C
